Gymnopus eneficola-species nova from Newfoundland

In the course of a survey of dried collections of Gymnopus collected over some years in Newfoundland by AV and Foray Newfoundland & Labrador, a taxon was discovered which did not conform to other known eastern North American or European taxa of the genus. Occasional reports of taxa now placed in Gymnopus (formerly included in an expansive concept of Collybia) include those concerning Nova Scotia, summarized by Gourley, and Michigan, none of which, nor those of the even older publication by Coker and Beardslee circumscribed the proposed species from Newfoundland. In addition to morphological distinctions, DNA analysis also indicated that nuclear ribosomal LSU and ITS sequences from the new taxon did not match those deposited in GenBank or sequences in the Gymnopus files at TENN. The new taxon is proposed, illustrated and described below.
